code_saturne User's Forum

Sorry, I found the problem. I checked boundary conditions twice and there was no deposition model. But I occasionally enabled the Turbulent deposition model in Particle and droplet tracking - Global settings (I hurried and messed it with turbulent dispersion because the word looks very similary). I ...

Hello. I need to do a cyclone modelling for my work. I made it with Saturne 4.0 and RSM turbulence model. The results are promising (resembling Fluent RSM results that I need to verify) but the target is not just a velocity profiles but also a cyclone efficiency. I cannot import Saturne's CGNS in Fl...

Yvan Fournier Thanks for suggestions about layers. But in my case this is just an errorneous mesh with negative cell volumes, not aspect ratio or so (BTW, geometry is very simple in layered area). I already posted the question on Salome forum (although, unfortunately, it's unlikely to get a help th...

Yvan Fournier Sorry, I made a mistake launching the calculation yesterday so it was running on a 20-million mesh without layers . I still think that the initial problem of this topic is solved (it was incorrect turbulence BC), but when I started the same variant on a mesh with layers it failed agai...

Yvan Fournier Thanks for your reply. The "20-million" case without layers is now running and seem to be stable. We are now waiting for OS and Ansys update on a cluster, any freeware "add-ons" are planned later (at best) so I still have to use Saturne only on a workstation (with ...

Hello. I simulate relatively simple "pure aerodynamic" case with Saturne. Initial (preliminary) variant is based on ~5 mln cells tetra mesh generated with NetGen in Salome. Flow algorythm is Static, k-epsilon turbulence model. This case runs OK and shows acceptable argeement with CFX resul...

Yvan Fournier I can't believe it but it's true. Valve cross-section from Catalyst output with live velocity profile is now on my laptop's screen . Fantastic :) I solved Python issue by turning back to version 2.6.6 (default on CentOS 6.5) and setting PATH, LD_LIBRARY_PATH and LD_PRELOAD as you reco...

Yvan Fournier Hello and thanks for suggestions. I thougth that python2.6 in call stack is due to Saturne's calls and it should be normal as you mentioned above... I will try to implement you advice as soon as possible, but now I have to take time for other important work... Update ======= I tested ...

Yvan Fournier I strongly recommend configuring Python with "--prefix" and running "make install" after "make". I did it this way (I just didn't mention it because it's usual), but the installation was in build dir (I know it's not very good but it worked OK with many p...

Yvan Fournier Unfortunately, trick with LD_LIBRARY_PATH didn't help. I checked that this path is correct by typing: ls $LD_LIBRARY_PATH There was the only Python directory in this variable so ls showed it's contents. Then I ran Code_saturne from the same terminal window and launched test simulation...
